I need to determine the propagation uncertainty of a calculated quanity (function of the variables mass, acceleration due to gravity, cap plate separation, and voltage), but I do not know the uncertainties of these measurements. I just know the values. What should I take the uncertainty to be? Should I just say +/- 0.5 or +/1 0.1 of the least significant digit? I missed the lab so I didn't actually perform the measurements, and the prof gave me this simulation program of the lab, but the simulation program says nothing about the uncertainties of the measurements. I am calculating charge from the following equation. q = (mgd)/v Examples of the values for the measured data are as follows... m = 1.x10x-15 kg v = 125 V d = 0.01 m g = 9.81 m/s^2 What should I take the uncertainties to be??
